Our hydra series includes hydra pen, hydra derma roller and hydra needles. They are also tools for hydra micro needling, and the most representative hydra pen would be hydra pen H2. Like many other micro needling tools, hydra series devices can create numerous micro needling injuries onto the skin, which brings more channels on the skin so that the skincare products can be absorbed more efficiently. In the meanwhile, the micro injuries will stimulate the self-healing process of the skin, during which process the collagen will regrow so that the skin will be refreshed and rejuvenated. Hydra series devices have all the functions of micro needling, which are smoothing wrinkles and fine lines, treating acne and pimples, balance skin tone, reducing pigmentation, minimizing large pores, tightening and lifting the skin and enhancing skin absorption efficacy.
